Remove support for ArduinoCore-Primo. (#55)

Browse Source 
The board is retired and the corresponding core (https://github.com/arduino/ArduinoCore-primo) has been archived. Considering that no one is going to maintain the low power code for nRF52/Primo its better to get rid of it alltogether (and no longer advertise compatibility to 'nrf52' which - imho rightfully - seems to confuse a lot of people.

PrimoDeepSleep.ino
Written by Chiara Ruggeri (chiara@arduino.org)
This example for the Arduino Primo board shows how to use
Arduino Low Power library to enter in power off mode and save power.
This mode ensures the deepest power saving mode. If you need
a faster response from the board use standby function instead.
Please note that once exited from the deepest sleep mode the
board will reset (so setup will be run again).
The functions enableWakeupFrom set the peripheral that will wake up
the board. By calling it more than once you can choose multiple
wakeup sources.
The board will be reset when it wakes up from power off.
You can use wakeUpCause() function to find out what signals woke up
the board if you use more than one wakeUpBy.. function.
This example code is in the public domain.

// enable USER1_BUTTON to turn STM32 off and on when pressed.
// note that when STM32 is off you cannot load any new sketch.
